Growth and Yield of Indian Mustard as Affected by Integrated Nutrient Management under Doon Valley Condition of Uttarakhand, India

Aims: To study the effects of integrated nutrient management practices on growth, and yield of Indian mustard.

Study Design: Randomized Block Design.

Place and Duration of Study: Agricultural Research Farm Doon (P.G.) College of Agricultural Science and Technology, Selaqui, Dehradun during rabi season (2023-2024).

Methodology: The experiment was laid out with three replication and ten treatments. The plot size was 4.5 m × 3m with high yielding variety ‘NRCHB 101’ was taken for the study.

Results: Significantly the highest growth parameters at harvest viz. plant height(199.33cm), number of primary and secondary branches(10.00 and15.66),leaf area index(3.64), dry matter (68.233 g plant-1),yield attributing characters i.e. length of siliquae (6.433cm), number of siliquae plant-1(323.667),number of seeds siliquae -1(13.333), test weight(5.57g), grain yield(21.813q ha-1), stover yield(71.343q ha-1), biological yield(93.157q ha-1), harvest index (23.407) were observed in T10 (75% RDF + FYM + Vermicompost + Azotobacter)and the lowest were observed in the in the T1.

Conclusion: The significantly higher grain yield was observed in T10 (75% RDF + Vermicompost @ (5 ton/ ha + FYM @ (10 ton/ ha + Azotobacter).
